Early performance of the tracking detector for the FASER experiment / Inada, Tomohiro (CERN) /FASER Collaboration
FASER is a new experiment aimed at searching for new light weakly-interacting long-lived particles and studying high-energy neutrino interactions in the very forward region of LHC collisions at CERN. The experimental setup is located 480 meters downstream from the ATLAS interaction point, aligned with the beam collision axis. [...]

The first test of a monolithic silicon pixel detector ASIC for the detection of electromagnetic showers of TeV energy in the FASER experiment at the LHC / Kotitsa, Rafaella Eleni (Geneva U.) /FASER Collaboration
The FASER experiment at the LHC is designed to look for new, long-lived fundamental particles. A W-Si preshower detector is currently under construction, with the objective of enabling the discrimination of photon pairs with O(TeV) energies and separation down to 200 μm, extending the discovery potential of the experiment.

Observation of high-energy electron neutrino interactions with FASER's emulsion detector at the LHC /FASER collaboration
This note presents the first results from the search for high energy electron and muon neutrino charged-current interactions in the FASER$\nu$ emulsion/tungsten sub-detector of FASER. A subset of the FASER$\nu$ volume is used, corresponding to a target mass of 68~kg, exposed to 9.5~$fb^{-1}$ of LHC proton-proton collision data with a centre of mass energy of 13.6~TeV. [...]

Commissioning of the FASER Trigger and Data Acquisition Prior to Proton-proton Collision Data-taking at the LHC / Antel, Claire /FASER Collaboration
FASER is a newly installed experiment at the LHC designed to search for long lived particles produced in high energy proton collisions and decaying several 100 meters downstream. As the experiment aims to measure a rare hypothetical process, it is crucial that the experiment’s trigger and data acquisition (TDAQ) system runs reliably and with minimal deadtime, quick to catch errors and raise alerts.

First Results from the Search for Dark Photons with the FASER Detector at the LHC /FASER collaboration
FASER is an LHC experiment designed to search for light, weakly-interacting particles that are produced in proton-proton collisions at the ATLAS interaction point and travel in the far-forward direction. The first results from a search for dark photons decaying to an electron-positron pair, using a dataset corresponding to an integrated luminosity of 27.0 fb$^{-1}$ collected at center-of-mass energy $\sqrt{s} = 13.6$ TeV in 2022 in LHC Run 3, are presented.

FASER’s Electromagnetic Calorimeter Test Beam Studies / Cavanagh, Charlotte (Liverpool U.) /FASER Collaboration
FASER, or the Forward Search Experiment, is a new experiment at CERN designed to complement the LHC’s ongoing physics program, extending its discovery potential to light and weakly interacting particles that may be produced copiously at the LHC in the far-forward region. New particles targeted by FASER, such as long-lived dark photons or axion-like particles, are characterised by a signature with two oppositely charged tracks or two photons in the multi-TeV range that emanate from a common vertex inside the detector. [...]

FASER: The Lifetime Frontier at the LHC and the Search for Dark Matter / Queitsch-Maitland, Michaela (CERN)
The Forward Search Experiment (FASER) is the newest experiment at CERN’s Large Hadron Collider (LHC) and is at the forefront of the lifetime frontier in the search for dark matter and other new phenomena. It is uniquely situated around 500 m from the LHC interaction point 1 (IP1) and will be able to detect the decays of new, low mass, weakly interacting particles which are thought to act as a mediator between the particles that make up ordinary matter and a new dark sector. [...]
